A WORD AT THE START. 15

 and it is possible that what you fail to discover during 

 your rambles will be learned by applying to the practi- 

 cal Uz Gaunt of your neighborhood. Such was my ex-

 have used in the body of the work are here repeated, with 

 the name now adopted by the systematists. This list will 

 prove, I hope, of some value to those interested in the
